Definitions
- This invention relates to an electrical connector, more particularly to a generally U-shaped electrical connector which has reinforced side walls that can be prevented from excessive flexure and breakage.
- a generally U-shaped electrical connector has a generally U-shaped connector housing into which a circuit board can be inserted.
- the generally U-shaped connector housing has two parallel side walls, each of which is formed with an integral board-retaining projection.
- the circuit board has two opposite sides with two opposed notches for engaging the projections to retain the circuit board on the connector.
- each of the side walls 10 has a pin hole 100 into which a pin 11 is inserted.
- the circuit board 13 slides over inclined surfaces 120 of the projections 12 to push the outer end portions 101 of the side walls 10 outwardly away from each other.
- bent outer end sections 110 of the pins 11 are pulled outwardly, thereby permitting disengagement of the circuit board 13 from the connector.
- the side walls 10 and the pins 11 may flex excessively and break.
- the object of this invention is to provide a generally U-shaped connector with reinforced side walls which can be prevented from excessive flexure and breakage.
- an electrical connector includes a generally U-shaped connector housing, which has two parallel side walls. Each of the side walls is formed with an integral projection, which engages a notch in a circuit board that is inserted into the connector. Two unitary reinforcing members are secured to the side walls, respectively. Each of the unitary reinforcing members has an elongated abutment plate overlying a respective one of the side walls to reinforce the side walls, two contact portions and a stop element, which is located between the contact portions.
- the circuit board slides over the projections of the side walls, thereby permitting flexing of the side walls and movement of the stop element relative to the contact portions.
- the stop element Upon contact of the stop element with either of the contact portions, the side walls cannot continue to flex. Accordingly, excessive flexure and breakage of the side walls can be prevented.
- FIG. 1 is a schematic view illustrating how a projection of a side wall of a conventional electrical connector is engaged within a notch in a circuit board;
- FIG. 2 is an elevational view of the preferred embodiment of an electrical connector according to this invention, in which two reinforcing members are removed;
- FIG. 3 is an exploded perspective view showing a side wall and one of the reinforcing members of the preferred embodiment
- FIG. 3A is a partly sectional end view showing the assembly of the side wall and the reinforcing member of FIG. 3;
- FIG. 4 illustrates the position of a stop element relative to two contact portions of the reinforcing member in the preferred embodiment
- FIG. 5 illustrates how a circuit board is inserted into the preferred embodiment.
- an electrical connector of this invention is shown to include a generally U-shaped connector housing 14, a terminal unit 15 and two unitary reinforcing members 16.
- the housing 14 is adapted to receive a circuit board 13' (see FIG. 5) therein.
- the generally U-shaped connector housing 14 is made of plastic, and has an elongated straight housing body 141 on which the terminal unit 15 is mounted, and two elongated parallel side walls 142, which are connected respectively and fixedly to two ends of the housing body 141.
- Each of the side walls 142 has an outer side surface (142A) (see FIG. 2) and an inner side surface (142B) (see FIG. 2), which are perpendicular to the circuit board 13' (see FIG. 5).
- Each of the inner side surfaces (142B) (see FIG. 2) has an inner end portion connected to the housing body 141, and an outer end portion, which is formed with an integral board-retaining projection 143.
- the projections 143 are adapted to engage respectively two notches 130' (see FIG.
- Each of the side walls 142 further has an outer groove 144 formed in the respective projection 143, and an inner groove 145 formed in a projecting block 146, which is formed integrally with the side wall 142.
- Each of the unitary reinforcing members 16 is made of a metal, and has an elongated abutment plate 160 which is perpendicular to the circuit board 13', an inner contact portion 161, an outer contact portion 162, and a stop element 163, which is located between the inner and outer contact portions 161, 162.
- the abutment plate 160 overlies the outer side surface 142A (see FIG. 2) of the side wall 142 to reinforce the side wall 142, and has an inner end portion located near the housing body 141, and an outer end portion away from the housing body 141.
- An inner extension portion 164 extends from the inner end portion of each of the abutment plates 160, and has a tongue portion 165, which is fitted within the inner groove 145 in the respective projecting block 146.
- An outer extension portion 166 extends from the outer end portion of each of the abutment plates 160, and has a lug portion 167, which is fitted within the outer groove 144 in the respective projection 143. Accordingly, the reinforcing members 16 are secured respectively to the side walls 142.
- each of the stop elements 163 is shaped as a flat plate, which is formed on the respective inner extension portion 164 and which is perpendicular to the respective abutment plate 160.
- Each of the inner contact portions 161 is shaped as a flat plate, which is formed in the respective outer extension portion 166 and which is parallel to the respective abutment plate 160.
- Each of the outer contact portion 162 is a portion of the respective abutment plate 160, which is aligned with the corresponding stop element 163.
- the stop element 163 is spaced apart from the contact portions 161, 162 at predetermined distances.
- the contact portions 161, 162 move relative to the stop elements 163.
- the side walls 142 can flex inwardly toward each other unit until the outer contact portion 162 contacts the stop elements 163, and can flex outwardly away from each other until the inner contact portion 161 contacts the stop elements 163.
- the inner contact portions 161 may be formed on the inner extension portions 164, while the stop elements 163 may be formed on the outer extension portions 165, as long as the stop elements 163, when flexed, can contact either the inner or outer contact portions 161.
